He told liverpoolfc.com: Of course it feels strange to be leaving.
There are two ways you feel. One, you have to make a decision at one point and we made this decision and we think, I think, it was the right decision.
So, that means there are reasons for your decision: if you don't feel anymore the right energy, the right focus, the right conviction, if things have a certain development and you come to this decision, it means that you know it's right. So, that is one part of the feelings.
The other part is, of course, that you look back at the journey. You start thinking about how it was when you came in, what could we achieve, how was the journey, how intense was it?
You think about the whole development of the club the stadium, the training ground, when we came in we were at Melwood the development of the players and of our relationships.
With all this there is only one conclusion: that it was a great, massive and successful journey and this comes to an end now. So, the feeling is strange because it was a big part of my personal life as well.
I lived here with my family, of course, and our boys came here when they were eight and six years old, so that is part of the feelings as well.
But the summary is that it was great, a massive experience. I learned a lot, there were a lot of fantastic moments and now it's time to say goodbye. There are a lot of things which will stay forever in my heart and my mind. So, it's cool but also a bit painful, of course."
